AI Article Synopsis
- Normal pressure hydrocephalus (NPH) is linked to symptoms like dementia, gait issues, and urinary incontinence, and genetic factors may influence its severity.
- The study examined the distribution of ApoE, ACT, and PS-1 genotypes in 13 NPH patients, finding no significant differences in ACT and PS-1 compared to controls.
- However, NPH patients showed a higher frequency of the ApoE epsilon4 allele, suggesting its potential role in the development of NPH.
Article Abstract
Normal pressure hydrocephalus (NPH) is characterized by dementia, gait disorders and urinary incontinence. Apolipoprotein E (ApoE) epsilon4 allele has been associated with severity of dementia in Alzheimer's disease (AD) and in other forms of dementia. Moreover, homozygosity of the A allele of the alpha1-antichymotrypsin (ACT) gene and of allele 1 of the presenilin-1 (PS-1) gene was associated with an increased risk for late onset AD. We analyzed the distribution of ApoE, ACT and PS-1 genotypes and the corresponding allele frequencies in 13 NPH patients. No differences were found in ACT and PS-1 polymorphism distributions in the patients studied with respect to the control group. An increased ApoE epsilon4 allele frequency was observed in NPH patients with respect to controls, thus suggesting that epsilon4 allele may also be involved in the pathogenesis of the disease.

Introduction: Traditional multivariate methods for neuroimaging studies overlook the interdependent relationship between brain features. This study addresses this gap by analyzing relative brain volumetric patterns to capture how Alzheimer's disease (AD) and genetics influence brain structure along the disease continuum.
Methods: This study analyzed data from participants across the AD continuum from the Alzheimer's and Families (ALFA) and Alzheimer's Disease Neuroimaging Initiative (ADNI) studies.

Objective: the ε4 allele of the apolipoprotein E gene (APOE4) is recognized as the primary genetic risk factor for Alzheimer's disease (AD) and has been associated with chronic inflammatory conditions, such as periodontal disease (PD). PD has been identified as having a potentiating effect that favors the development and progression of AD. This scoping review investigates the potential relationship between PD and AD through APOE4 METHODS: the Joanna Briggs Institute methodology was used.

Background: The effect of statins use on the incidence of Alzheimer's disease (AD) is still under debate, and it could be modified by a series of factors.
Objectives: We aimed to examine the association of statins use with the risk of cognitive impairment and AD, and assess the moderating roles of genetic susceptibility and other individual-related factors.
Design: A longitudinal study was conducted from the UK Biobank where individuals completed baseline surveys (2006-2010) and were followed (mean follow-up period: 9 years).

Alzheimer's disease (AD), the leading cause of dementia, significantly impacts global public health, with cases expected to exceed 150 million by 2050. Late-onset Alzheimer's disease (LOAD), predominantly influenced by the APOE-ε4 allele, exhibits complex pathogenesis involving amyloid-β (Aβ) plaques, neurofibrillary tangles (NFTs), neuroinflammation, and blood-brain barrier (BBB) disruption. Proteomics has emerged as a pivotal technology in uncovering molecular mechanisms and identifying biomarkers for early diagnosis and intervention in AD.

Apolipoprotein E (ApoE), especially the ApoE4 isotype, is suggested to influence the severity of respiratory viral infections; however, this association is still unclear. The presence of allele ε4 impacts the development of flu-like syndromes. This study aimed to evaluate the impact of the Apo E4 isoform on the severity and duration of flu-like syndromes, including the coronavirus disease COVID-19.
